      (1)   New source compliance deadline. New sources shall install, calibrate and have in acceptable operating condition and shall start-up all pollution control equipment required to meet applicable pretreatment standards before beginning to discharge waste into the City's wastewater collection and treatment facilities. Within the shortest feasible time, not to exceed 90 days, new sources must meet all applicable pretreatment standards set forth in 40 C.F.R. 403.6(b).
      (2)   Baseline monitoring report.
         A.   Within either 180 days after the effective date of a categorical Pretreatment Standard, or the final administrative decision on a category determination under 40 C.F.R. 403.6(a)(4), whichever is later, existing categorical industrial users currently discharging to or scheduled to discharge to the POTW shall submit to the Control Authority a report which contains the information listed in paragraph B, below. At least 90 days prior to commencement of discharge, new sources, and sources that become categorical industrial users subsequent to the promulgation of an applicable categorical standard, shall be submit to the Control Authority a report which contains the information listed in divisions B.1 through B.8. below. A new source shall report the method of pretreatment it intends to use to meet applicable categorical standards. A new source also shall give estimates of the information requested in divisions B.5. and B.6. below.
         B.   Users described in division A. above shall submit the information set forth below:
            1.   Identifying information. The name and address of the facility including the name of the operator and owners;
            2.   Permits. A list of any environmental control permits held by or for the facility;
            3.   Description of operations. A brief description of the nature, average rate of production (including each product produced by type, amount, processes, and rate of production), and standard industrial classifications of the operation(s) carried out by such user. This description should include a schematic process diagram, which indicates points of discharge to the POTW from the regulated processes.
            4.   The location for monitoring all wastes covered by the permit.
            5.   Flow measurement. Information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from regulated process streams and other streams, as necessary, to allow use of the combined waste stream formula set out in 40 C.F.R. 403.6(e). (See division 6.e. below.) The Control Authority may allow for verifiable estimates of these flows where justified by cost or feasibility considerations.
            6.   Measurement of pollutants.
               a.   The Categorical Pretreatment Standards applicable to each regulated process and any new categorically regulated processes for existing sources.
               b.   The results of sampling and analysis identifying the nature and concentration, and/or mass, where required by the standard or by the Control Authority, of regulated pollutants in the discharge from each regulated process.
               c.   Instantaneous, daily maximum, and long-term average concentrations, or mass, where required, shall be reported.
               d.   The sample shall be representative of daily operations and shall be analyzed in accordance with procedures set out in division e. below. Where the standard requires compliance with a BMP or pollution prevention alternative, the user shall submit documentation as required by the Control Authority or the applicable standards to determine compliance with the standard.
               e.   The user shall take a minimum of one representative sample to compile that data necessary to comply with the requirements of this division e. Samples should be taken immediately downstream from pretreatment facilities if such exist or immediately downstream from the regulated process if no pretreatment exists. If other wastewaters are mixed with the regulated wastewater prior to pretreatment the user should measure the flows and concentrations necessary to allow use of the combined wastestream formula of C.F.R. 40 Part 403.6(e) in order to evaluate compliance with the pretreatment standards. Where an alternate concentration or mass limit has been calculated in accordance with C.F.R. 40 Part 403.6(e) this adjusted limit along with supporting data shall be submitted to the Control Authority.
               f.   Sampling and analysis shall be performed in accordance with the techniques prescribed in 40 C.F.R. part 136 and amendments thereto. Where 40 C.F.R. part 136 does not contain sampling or analytical techniques for the pollutant in question, or where the Administrator determines that the 40 C.F.R. part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analysis shall be performed by using validated analytical methods or any other applicable sampling and analytical procedures, including procedures suggested by the POTW or other parties, approved by the Administrator.
               g.   The Control Authority may allow the submission of a baseline report which utilizes only historical data so long as the data provides information sufficient to determine the need for industrial pretreatment measures;
               h.   The baseline report shall indicate the time, date and place, of sampling, and methods of analysis, and shall certify that such sampling and analysis is representative of normal work cycles and expected pollutant Discharges to the POTW;
               i.   For sampling required in support of baseline monitoring and 90-day compliance reports, a minimum of four grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide and volatile organic compounds for facilities for which historical sampling data do not exist; for facilities for which historical sampling data are available, the Control Authority may authorize a lower minimum. For other required reporting and assessment of compliance, the Control Authority shall require the number of grab samples necessary to assess and assure compliance by industrial users with applicable Pretreatment Standards and Requirements;
               j.   All users reports must be based upon data obtained through appropriate sampling and analysis performed during the period covered by the report, which data are representative of conditions occurring during the reporting period. The Control Authority shall require that frequency of monitoring necessary to assess and assure compliance by industrial users with applicable Pretreatment Standards and Requirements. Grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide, and volatile organic compounds. For all other pollutants, 24-hour composite samples must be obtained through flow-proportional composite sampling techniques, unless time-proportional composite sampling or grab sampling is authorized by the Control Authority. Where time-proportional composite sampling or grab sampling is authorized by the Control Authority, the samples must be representative of the Discharge and the decision to allow the alternative sampling must be documented in the industrial user file for that facility or facilities. Using protocols (including appropriate preservation) specified in 40 C.F.R. part 136 and appropriate EPA guidance, multiple grab samples collected during a 24- hour period may be composited prior to the analysis as follows: For cyanide, total phenols, and sulfides the samples may be composited in the laboratory or in the field; for volatile organics and oil & grease the samples may be composited in the laboratory. Composite samples for other parameters unaffected by the compositing procedures as documented in approved EPA methodologies may be authorized by the Control Authority, as appropriate.
            7.   Certification. A statement, reviewed by an authorized representative of the industrial user (as defined in § 1041.02) and certified to by a qualified professional, indicating whether Pretreatment Standards are being met on a consistent basis, and, if not, whether additional operation and maintenance (O and M) and/or additional Pretreatment is required for the industrial user to meet the Pretreatment Standards and Requirements.
            8.   Compliance schedule. If additional pretreatment technology and/or O and M will be required to meet the Pretreatment Standards; the shortest schedule by which the industrial user will provide such additional pretreatment and/or O and M. The completion date in this schedule shall not be later than the compliance date established for the applicable Pretreatment Standard.
               a.   Where the industrial user's categorical Pretreatment Standard has been modified by a removal allowance (40 C.F.R. 403.7), the combined wastestream formula (40 C.F.R. 403.6(e)), and/or a fundamentally different factors variance (40 C.F.R. 403.13) at the time the user submits the report required by division B. above, the information required by divisions B.6. and B.7. above of this section shall pertain to the modified limits.
               b.   If the categorical Pretreatment Standard is modified by a removal allowance (40 C.F.R. 403.7), the combined wastestream formula (40 C..F.R. 403.6(e)), and/or a Fundamentally Different Factors variance (40 C.F.R. 403.13) after the user submits the report required by division B. above of this section, any necessary amendments to the information requested by divisions b.6. and b.7. above of this section shall be submitted by the user to the Control Authority within 60 days after the modified limit is approved.
      (3)   Periodic compliance reports.
         A.   Any industrial user subject to a Categorical Pretreatment Standard after the compliance date of such Pretreatment Standard, or, in the case of a New Source, after commencement of the discharge into the POTW, shall submit to the Control Authority during the months of June and December, unless required more frequently in the Pretreatment Standard or by the Control Authority or the Approval Authority, a report indicating the nature and concentration of pollutants in the effluent which are limited by such categorical Pretreatment Standards. In addition, this report shall include a record of measured or estimated average and maximum daily flows for the reporting period. The Control Authority may, at its discretion, require more detailed reporting of flows. In cases where the Pretreatment Standard requires compliance with a Best Management Practice (or pollution prevention alternative), the user shall submit documentation required by the Control Authority or the Pretreatment Standard necessary to determine the compliance status of the user. At the discretion of the Control Authority and in consideration of such factors as local high or low flow rates, holidays, budget cycles, etc., the Control Authority may modify the months during which the above reports are to be submitted.
         B.   Reporting requirements for industrial users not subject to categorical Pretreatment Standards. The Control Authority must require appropriate reporting from those industrial users with discharges that are not subject to categorical Pretreatment Standards. Significant Non-categorical Industrial Users must submit to the Control Authority at least once every six months (on dates specified by the Control Authority) a description of the nature, concentration, and flow of the pollutants required to be reported by the Control Authority. In cases where a local limit requires compliance with a Best Management Practice or pollution prevention alternative, the user must submit documentation required by the Control Authority to determine the compliance status of the user. These reports must be based on sampling and analysis performed in the period covered by the report, and in accordance with the techniques described in 40 C.F.R. part 136 and amendments thereto. This sampling and analysis may be performed by the Control Authority in lieu of the significant non-categorical industrial user. If a user subject to the reporting requirements of this section monitors any regulated pollutant at the appropriate sampling location more frequently than required by the Control Authority, the results of this monitoring shall be included in the report.
         C.   1.   If the results of periodic monitoring indicate noncompliance with any pollutant limit stipulated in the industrial user's discharge permit, or where such limits or permits do not exist, or where monitoring results exceed Federal categorical or local limits, the industrial user shall notify the Public Works & Utilities Director in writing within 24 hours of becoming aware of this nonconforming discharge. The industrial user must then repeat the sampling and analysis and submit the results to the City within 45 days, unless the City samples the industrial user's discharge. If this re- sampling indicates continued noncompliance, then the industrial user shall continue weekly sampling until such time that the results of two repeat samplings indicate a return to compliance status. Results of all such re-sampling must be received by the City within 45 days following such re-sampling. If the City conducts monitoring and becomes aware of a permit violation or parameter exceedance, the City will either conduct the resampling within 30 days or will require the industrial user to resample as described below.
            2.   Re-sampling, as described above, may also be ordered when the City, as a result of its own sampling efforts, discovers a violation of discharge limits. The City will notify the industrial user of a violation and provide a re-sampling schedule to the industry as part of this notification.
            3.   The re-sampling, as described in this division, is not required of any industry monitored on a daily basis by the City.
      (4)   Compliance schedule progress reports. The following conditions shall apply to the compliance schedule required by § 1041.05(c)(2)B.8.:
         A.   The schedule shall contain progress increments in the form of dates for the commencement and completion of major events leading to the construction and operation of additional pretreatment required for the user to meet the applicable pretreatment standards (such events include, but are not limited to, hiring an engineer, completing preliminary and final plans, executing contracts for major components, commencing and completing construction, and beginning and conducting routine operation).
         B.   No increment referred to above shall exceed nine months.
         C.   The user shall submit a progress report to the Director no later than 14 days following each date in the schedule and the final date of compliance including, as a minimum, whether or not it complied with the increment of progress, the reason for any delay, and, if appropriate, the steps being taken by the user to return to the established schedule.
         D.   In no event shall more than nine months elapse between such progress reports to Director.
      (5)   Reports on compliance with categorical pretreatment standard deadline. Within 90 days following the date for final compliance with applicable categorical pretreatment standards, or in the case of a new source following commencement of the introduction of wastewater into the POTW, any user subject to such pretreatment standards and requirements shall submit to the Director a report containing the information described in § 1041.05(c)(2)B.5. and 6. above. For users subject to equivalent mass or concentration limits established in accordance with the procedures in § 1041.03(b)(1) of this chapter, shall contain a reasonable measure of the user's long-term production rate. For all other users subject to categorical pretreatment standards expressed in terms of allowable pollutant discharge per unit of production (or other measure of operation), this report shall include the user's actual production during the appropriate sampling period. All compliance reports must be signed and certified in accordance with § 1041.07 of this chapter.
      (6)   Reports of potential problems.
         A.   In the case of any discharge, including, but not limited to, accidental discharges, discharges of a nonroutine, episodic nature, a noncustomary batch discharge, a slug discharge or slug load, that might cause potential problems for the POTW, the user shall immediately telephone and notify POTW of the incident. This notification shall include the location of the discharge, type of waste, concentration and volume, if known, and corrective actions taken by the user.
         B.   Within five days following such discharge, the user shall, unless waived by the Public Works & Utilities Director or their designee, submit a detailed written report describing the cause(s) of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage, or other liability which might be incurred as a result of damage to the POTW, natural resources, or any other damage to person or property; nor shall such notification relieve the user of any fines, penalties, or other liability which may be imposed pursuant to this chapter.
         C.   A notice shall be permanently posted on the user’s bulletin board or other prominent place advising employees who to call in the event of a discharge described in division (6)A., above. Employers shall ensure that all employees, who could cause such a discharge to occur, are advised of the emergency notification procedure.
         D.   Significant industrial users are required to notify the Director immediately of any changes at its facility affecting the potential for a slug discharge.
   (d)   Monitoring Facilities. 
      (1)   Each industrial user shall provide and operate, at the user's expense, a monitoring facility to allow inspection, sampling and flow measurement of each sewer discharge to the City. Each monitoring facility shall be situated on the user's premises, except where such a location would be impractical or cause undue hardship on the user, in which case the City may concur with the facility being constructed in the public street or sidewalk area, provided that the facility is located so that it will not be obstructed by landscaping or parked vehicles.
      (2)   There shall be ample room in or near such sampling facility to allow accurate sampling and preparation of samples for analysis. The facility, sampling, and measuring equipment shall be maintained at all times in a safe and proper operating condition at the expense of the user.
      (3)   All monitoring facilities shall be constructed and maintained in accordance with the applicable local construction standards and specifications.
      (4)   Record keeping requirements. Self-monitoring, sampling, reporting, notification and recordkeeping requirements, including an identification of the pollutants to be monitored (including the process for seeking a waiver for a pollutant neither present nor expected to be present in the discharge in accordance with 40 C.F.R. § 403.12(e)(2), or a specific waived pollutant in the case of an individual control mechanism), sampling location, sampling frequency, and sample type, based on the applicable general pretreatment standards in 40 C.F.R part 403, categorical pretreatment standards, local limits, and state and local law. Users subject to the reporting requirements of this chapter shall retain, and make available for inspection and copying, all records of information obtained pursuant to any monitoring activities required by this chapter, any additional records of information obtained pursuant to monitoring activities undertaken by the user independent of such requirements, and documentation associated with Best Management Practices. Records shall include the date, exact place, method, and time of sampling, and the name of the person(s) taking the samples; the dates analyses were performed; who performed the analyses; the analytical techniques or methods used; and the results of such analyses. These records shall remain available for a period of at least three years. This period shall be automatically extended for the duration of any litigation concerning the user or the City, or where the user has been specifically notified of a longer retention period by the Public Works & Utilities Director.
   (e)   Analytical Requirements. All pollutant analyses, including sampling techniques, to be submitted as part of a wastewater discharge permit application or report shall be performed in accordance with the techniques prescribed in 40 C.F.R. part 136 and amendments thereto, unless otherwise specified in an applicable categorical pretreatment standard. If 40 C.F.R. part 136 does not contain sampling or analytical techniques for the pollutant in question, or where the EPA determines that the part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analyses shall be performed by using validated analytical methods or any other applicable sampling and analytical procedures, including procedures suggested by the Public Works & Utilities Director, their designee or other parties approved by EPA.
   (f)   Sample Collection. Samples collected to satisfy reporting requirements must be based on data obtained through appropriate sampling and analysis performed during the period covered by the report, based on data that is representative of conditions occurring during the reporting period.
      (1)   The reports required in this section must be based upon data obtained through appropriate sampling and analysis performed during the period covered by the report, which data are representative of conditions occurring during the reporting period. The Control Authority shall require that frequency of monitoring necessary to assess and assure compliance by industrial users with applicable pretreatment standards and requirements. Grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide, and volatile organic compounds. For all other pollutants, 24-hour composite samples must be obtained through flow-proportional composite sampling techniques, unless time-proportional composite sampling or grab sampling is authorized by the Control Authority. Where time-proportional composite sampling or grab sampling is authorized by the Control Authority, the samples must be representative of the discharge and the decision to allow the alternative sampling must be documented in the industrial user file for that facility or facilities. Using protocols (including appropriate preservation) specified in 40 C.F.R. part 136 and appropriate EPA guidance, multiple grab samples collected during a 24-hour period may be composited prior to the analysis as follows: For cyanide, total phenols, and sulfides the samples may be composited in the laboratory or in the field; for volatile organics and oil and grease the samples may be composited in the laboratory. Composite samples for other parameters unaffected by the compositing procedures as documented in approved EPA methodologies may be authorized by the Control Authority, as appropriate.
      (2)   For sampling required in support of baseline monitoring and 90-day compliance reports required in divisions (b) and (d) of this section, a minimum of four grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide and volatile organic compounds for facilities for which historical sampling data do not exist; for facilities for which historical sampling data are available, the Control Authority may authorize a lower minimum. For the reports required by divisions (b) through (g) of this section, the Control Authority shall require the number of grab samples necessary to assess and assure compliance by industrial users with applicable pretreatment standards and requirements.
   (g)   Right of Entry for Inspection, Sampling and Records Examination. The City may inspect all facilities of all users, including process/manufacturing operations, pretreatment systems and discharge monitoring facilities to determine compliance with the requirements of these regulations. The user shall allow the City or its representatives, upon presentation of credentials of identification, to enter upon the premises of the user on a 24 hour/7 day basis, for the purposes of inspection, sampling, records examination, records copying and the performance of any additional duties deemed appropriate by the City’s representative. Should the City’s representative discover a significant permit violation that may threaten the public, the collection system or the performance of the POTW, the City's representative shall have the authority to immediately order the user to terminate discharge to the City's sewerage system. The City shall have the right to set up on the user’s property such devices as are necessary to conduct sampling, inspection, compliance monitoring and/or metering operations. The City may require the user to install monitoring equipment as necessary. The facility’s sampling and monitoring equipment, upon approval by the City, shall be maintained at all times in a safe and proper operating condition by the user at its own expense. All devices used to measure wastewater flow and quality shall be calibrated monthly to ensure their accuracy. Any temporary or permanent obstruction to safe and easy access to the facility to be inspected and/or sampled shall be promptly removed by the user at the verbal order of the City’s representative. The cost of clearing and maintaining safe access shall be borne by the user.
